TO ALL WHOM I'I MAY CONCERN:

-Be it known that I, ROBERT WoLrr, of the city, county, and State of New York, have invented a new and useful improvement in Brick-Making Machines; and do hereby declare that the following is a full, clear," and exact deseriptionof the saine, reference being had to the accompanying drawings, of which- 'I l Figure l is a plan of my invention.

Figure 2 is a bottom view.

Figure 3 is a side elevation.

Figure l is an end elevation.

Figure 5 is a vertical longitudinal section, taken in the line :t 2:, fig. 4.

Figure 6 is a vertical cross-section, taken in the line y y, tig. 3.

Similar letters of reference indicate like parts. v

This invention relateslto new anduseful improvements in brick machines, whereby a cheap, simple, and efficient machine is produced, as hereinafter explained.

A, inthe accompanying drawings, is the mud box; B b b (frgb) is the kneading or grinding-shaft or knives. This shaft is driven by a pulley,-G, or by other suitable means. The mud box A is mounted on a framework or table, fm, and has, on two opposite sides, at its bottom, pockets or moulding-chambers D D, (gs. 5. and 6.) lhe throats a of these chambers, connecting the chambers with the mud box, are closed at each moulding by slides ll, (figs. 5 and 6,) each of these slides being operated by a lever, G, (figs. 4 and 6,) which is hung on a pivot, g, at its centre, and is actuated by a ca'mf, P p, (iig. 4,) on the shaft F. The top of ea'ch mouldingchamber D has a sliding cover, k, and these -covers areoperated by elbow-levers z' and I, (figs. 3 and 6,) which receive motion from cams S Sftlgs. 4 and 5) on the shaft F. The bottoms of the moulding-pockets or chambers D D are formed by plungers E yand c, (figs. 5 and 6,) which slide vertically therein, and are operated by earns R R on the shaft F. The saidshaft F is driven by a pulley, f, or by any suitable means. After the levers It; G G have been acted upon by their cams, their return or backward strokes are made by means of springs; 'lhus the machine has two sets of moulding-chambers'and operating appliances, and, if desired, either set may be shut off from moulding by a vertical hand-slide, v, (figs. 5 and 6,) which closes thethroat leading from the mud box to its moulding-pocket, and thus shuts oif the supply of clay and makes that side of the machine inopera tive. Or, both of these slides e may be closed, when the machine is first started, until the clay has been properly kneaded or tempered, when one or both are raised, as desired, and the moulding allowed to proceed.

Its operation is as follows: By theA time the clay in the mud box has reached its bottom it is suitably tempered, and one of the slides H being withdrawn the pocket of that side is filled by the pressure of the knives I1, and the throat a of the pocket is `immediately closed by means of its sliding-door H, which is operated by the lever G and cam P; the cover c of this pockeubeing also Closed, the plunger E or e'is then driven up forcibly by its' cam R, and the brick is formed and pressed to any desired extenbt. The working face of the cum R is of such form that, after the brick has been pressed sufficiently, the cam then, for amonient, remains neutral, while the corner of the cam S (of this side or set) strikes upon the lever I orz'and thereby slides the cover back from over the pocket. By thc time that the cover 7c has been thrown off, the neutral part of cam R has passed the plunger, andthe cam It again begins to act, and the plunger E is forced up until the brick is thrownout of the pocket D on to the table m., when the sliding-cover lc is-thrown forward and, catching `the brick, ,pushes it forward on toV a conveying-bolt, `t, running over pulleys T T, (fig. 6,) and the brick is con-A veyed oif out of the way. This description of the operation of one side or set of the moulding apparatus will answer for both sides, as their. construction and action are the same; but the two sets act-alternately, so that the work is distributed more cvcnlyon the moving power than if the plungers made their pressing strokes simultane= ously. 'Ihe moulding-pockets D and plungers Emay bc so modied in their construction that more than one brick may be moulded and delivered at a single stroke of either plunger; however, I consider the present method as the more preferable.l These machines may be constructed with a single set of moulding apparatus, as shown upon one side, or the apparatus may be duplicated, as shown. Furthermore, itis well known to those cenyersant with the nrt of making iire or pressed brick, that they are rst moulded by hand or otherwise, and then dried, and are then `placed in a machine and submitted to pressure, consuming much time and labor, when, by my machine, the operation of moulding -and pressing is performed :it a. single operation; and, the moisture being sufficiently pressed out, the bricks are ready for the kiln as they are delivered from the machine.

Having thus described my invention, what I claim'as new, and desire to secure by Letters Patent, is-

1: I claim, in connection with the mud box A, und grindingshnft B b, the moulding-pocket D, slidingcover 7c, throdt-slide H, plunger E, levers G I, and ooms P R S, all constructed, arranged, und operating substantially ns and for the purpose herein described.

42. I claim o. duplication of thefabove in connection with n. single mud box A, sindn grinding device B b b,

substantially in the manner and for the purpose hereinbe'ore described,
